◆ can_unit_change_homecity_to()

bool can_unit_change_homecity_to ( const struct civ_map nmap,

Return TRUE iff the unit can change homecity to the given city.

◆ can_unit_do_activity()

bool can_unit_do_activity ( const struct civ_map nmap,
const struct unit punit,
enum unit_activity  activity

Return TRUE iff the unit can do the given untargeted activity at its current location.

Note that some activities must be targeted; see can_unit_do_activity_targeted().

◆ can_unit_do_autosettlers()

bool can_unit_do_autosettlers ( const struct unit punit)

Return whether the unit can be put in auto-settler mode.

NOTE: we used to have "auto" mode including autosettlers and auto-attack. This was bad because the two were indestinguishable even though they are very different. Now auto-attack is done differently so we just have auto-settlers. If any new auto modes are introduced they should be handled separately.

◆ can_unit_paradrop()

bool can_unit_paradrop ( const struct civ_map nmap,
const struct unit punit 
)

Return whether the unit can be paradropped - that is, if the unit is in a friendly city or on an airbase special, has enough movepoints left, and has not paradropped yet this turn.

◆ can_unit_unload()

bool can_unit_unload ( const struct unit pcargo,
const struct unit ptrans 
)

Return TRUE iff the given unit can be unloaded from its current transporter.

This function checks everything except the legality of the position after the unloading. The caller may also want to call can_unit_exist_at_tile() to check this, unless the unit is unloading and moving at the same time.

int get_activity_rate ( const struct unit punit)

Returns the speed of a unit doing an activity. This depends on the veteran level and the base move_rate of the unit (regardless of HP or effects). Usually this is just used for settlers but the value is also used for military units doing fortify/pillage activities.

The speed is multiplied by ACTIVITY_FACTOR.
